CYLINDER WORKS offers this top-end gasket kit for YAMAHA WR 450 F, YFZ 450, YZ 450 F from 2003 to 2013. The top end is the cylinder, piston and cylinder head. When they are taken apart, the gaskets sealing them are crushed and cannot be reused.

Why buy a complete kit?

The benefits:

• Every top-end gasket in one part number: nothing is forgotten at reassembly.
• Cheaper than buying the gaskets one by one.
• New gaskets guarantee compression and sealing against water, oil and gases.

Why choose CYLINDER WORKS?

Cylinder Works supplies brand-new, not remanufactured, cylinders with a nickel-silicon-carbide coating; its kits come with a matched forged Vertex piston.

When should you replace the gaskets on your YAMAHA YFZ 450?

An oil or coolant leak, seepage around the cases or a loss of compression signal a tired gasket. Having the kit to hand means the bike is never stuck waiting for one missing gasket.
